Who Litters and Why People Litter?

Along roadways, motorists (52%) and pedestrians (23%) are the biggest contributors to litter. Research also shows that individuals under 30 are more likely to litter than those who are older. In fact, age, and not gender, is a significant predictor of littering behavior.

Personal choice. Individual behavior—or choosing to litter—means litter on the ground. Nearly one in five, or 17% of all disposals observed in public spaces were littering, while 83% disposed of litter properly. And 81% of littering was intentional, e.g., flicking, flinging, or dropping. On the other hand, individuals who hold the belief that littering is wrong, and consequently feel a personal obligation not to litter, are less likely to do so.

Litter begets litter. Individuals are much more likely to litter into a littered environment. And once there, it attracts more litter. By contrast, a clean community discourages littering and improves overall community quality of life. Availability and proximity to trash and recycling receptacles also impact whether someone chooses to litter.

It’s “not my responsibility”. Some people feel no sense of ownership for parks, walkways, beaches, and other public spaces. They believe someone else will pick up after them; that it’s not their responsibility.
